Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically to an integrated mechanism for isolating electric and grounding manual operation. Background Technology

[0002] Currently, switchgear typically contains two to four disconnecting switches and grounding switches. Each switch requires an electric actuator, resulting in a large switchgear size and high production costs. To meet market demands and for safety reasons, disconnecting switches, which are operated more frequently, are typically electrically operated, while grounding switches are only used during maintenance and are operated less frequently. Since maintenance requires on-site personnel, grounding switches are operated manually, which addresses both practical operational needs and reduces production costs.

[0003] For example, Chinese utility model patent CN215897140U discloses a grounding switch and handcart interlocking mechanism for miniaturized switchgear. It mainly addresses the problem that existing grounding switch and handcart interlocking mechanisms cannot be applied to miniaturized switchgear. By using a grounding switch transmission component, a welded rotating rod, and an interlocking transmission device, the power of the grounding switch opening and closing is converted into the movement force of the interlocking limit plate and the limit plate block. When the limit plate extends, it blocks the handcart limit plate and the handcart interlocking limit plate, preventing the handcart from being driven. When the limit plate retracts, the handcart limit plate and the handcart interlocking limit plate are in a free and unrestricted state, allowing the handcart to be driven. This realizes the interlocking of the grounding switch and the handcart in miniaturized switchgear, effectively ensuring the safety of miniaturized switchgear.

[0004] For example, Chinese utility model patent CN207503836U discloses a padlock device for a grounding switch of a switchgear, including a mounting plate with an operating hole and an operating hole baffle for blocking the operating hole. One side of the operating hole baffle is hinged to one side of the mounting plate, and both the other side of the operating hole baffle and the other side of the mounting plate are provided with padlock holes. A channel is provided between the mounting plate and the operating hole baffle for the interlocking baffle of the switchgear to move up and down. This utility model has advantages such as eliminating interference, simplifying electric operation steps, and reducing the error rate of electric operation.

[0005] However, in the current market, electric and manual mechanisms are separate, requiring two separate mechanisms, which takes up a lot of space, and interlocking between the two mechanisms is difficult to achieve. Therefore, we propose an integrated mechanism that isolates electric and grounded manual mechanisms to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an integrated electric and grounding manual isolation mechanism to solve the problems mentioned in the background art, where the electric and manual mechanisms are currently separate, requiring two mechanisms, occupying a large space, and making it difficult to achieve interlocking between the two mechanisms.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated mechanism for isolating electric and grounding manual functions, comprising a mechanism box, a panel disposed outside the mechanism box, and a manual mechanism and an electric mechanism body disposed on the inner sides of the left and right ends of the mechanism box, respectively;

[0008] Also includes:

[0009] The electric mechanism body and the manual mechanism are used to operate the disconnect switch and the grounding switch, respectively, and the manual mechanism consists of a manual operation disc, a pin, a locking pin and a return spring.

[0010] Preferably, a manual operation disc is connected to the inner left side of the mechanism box via a pin shaft, and the outer end of the manual operation disc has an arc-shaped notch.

[0011] Preferably, the outer end of the manual operation disc is a circumferential surface, and two limiting grooves are formed on the circumferential surface.

[0012] Preferably, a locking pin is provided below the manual operation disc to engage with the mechanism box, and a reset spring is nested on the outer side of the lower end of the locking pin to fit against the mechanism box.

[0013] Preferably, the locking pin is telescopically connected to the mechanism box via a reset spring, and the upper end of the locking pin is snapped into the limiting groove.

[0014] Preferably, a semi-circular block located below the front end of the manual operation disc is fitted to the front side of the locking pin, and an electric mechanism spindle is installed on the inner side of the semi-circular block.

[0015] Preferably, the two ends of the semicircular block are a straight edge and a circular arc profile, respectively, and the outer arc of the circular arc profile is the same as the inner arc of the circular arc notch.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the integrated electric isolation and manual grounding mechanism has a compact structure, which can save installation space and facilitate user installation, make it easy to ensure the correct opening and closing position, and facilitate the interlocking of grounding and isolation operations;

[0017] 1. It is equipped with a mechanism box, a panel, an electric mechanism body and a manual mechanism. Since the panel is installed on the outside of the mechanism box, and the manual mechanism and the electric mechanism body are respectively installed on the inner side of the left and right ends of the mechanism box, the mechanism structure is compact, which can save installation space and facilitate user installation.

[0018] 2. It is equipped with an electric mechanism body, a manual mechanism, a manual operation disc and a semi-circular block. Since there is a mechanical interlock between the electric mechanism body and the manual mechanism, the manual operation disc has an arc-shaped notch. The left end of the electric mechanism main shaft is equipped with a semi-circular block. The outer end of the manual operation disc has two limit grooves on its circumferential surface. When in the open or closed position, the locking pin is pushed into the limit groove under the action of the return spring. When the open or closed position is in place, the manual operation disc is locked, thus ensuring that the open or closed position is correct.

[0019] 3. It is equipped with a manual operation disc, a locking pin, a semi-circular block, and an electric mechanism spindle. The semi-circular block located on the lower front side of the manual operation disc is attached to the front side of the locking pin. The electric mechanism spindle is installed on the inner side of the semi-circular block. The two ends of the semi-circular block are a straight edge and an arc contour, respectively. The outer arc of the arc contour is the same as the inner arc of the arc notch, which facilitates the interlocking of grounding and isolation operations. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4This utility model provides a technical solution: an integrated electric isolation switch and a manual grounding switch mechanism, comprising a mechanism box 1, a panel 2, an electric mechanism body 3, a manual mechanism 4, a manual operation disc 5, an arc-shaped notch 501, a circumferential surface 502, a limiting groove 503, a pin 6, a locking pin 7, a return spring 8, a semi-circular block 9, a straight edge 901, an arc contour 902, and an electric mechanism main shaft 10. The panel 2 is provided outside the mechanism box 1, and the manual mechanism 4 and the electric mechanism body 3 are respectively provided on the inner sides of the left and right ends of the mechanism box 1. The electric mechanism body 3 and the manual mechanism 4 are used to operate the isolation switch and the grounding switch, respectively. The manual mechanism 4 is composed of the manual operation disc 5, the pin 6, the locking pin 7, and the return spring 8.

[0027] The left inner side of the mechanism box 1 is connected to a manual operation disc 5 via a pin shaft 6. The outer end of the manual operation disc 5 has an arc-shaped notch 501. The outer end of the manual operation disc 5 is a circumferential surface 502, and two limiting grooves 503 are provided on the circumferential surface 502. A locking pin 7 is provided below the manual operation disc 5 and engages with the mechanism box 1. A return spring 8 is nested on the outer side of the lower end of the locking pin 7 and fits against the mechanism box 1. The locking pin 7 is telescopically connected to the mechanism box 1 via the return spring 8. The upper end of the locking pin 7 is snapped into the limiting groove 503. A semi-circular block 9 is fitted on the front side of the locking pin 7 and located on the lower side of the front end of the manual operation disc 5. An electric mechanism spindle 10 is installed on the inner side of the semi-circular block 9. The two ends of the semi-circular block 9 are a straight edge 901 and an arc contour 902, respectively. The outer arc of the arc contour 902 is the same as the inner arc of the arc-shaped notch 501.

[0028] To address the problems in existing technologies where the electric mechanism body 3 and the manual mechanism 4 are separate, requiring two mechanisms, resulting in significant space consumption, and where interlocking between the two mechanisms is difficult, this embodiment employs the following technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 4 The mechanism box 1 has a panel 2 installed on its exterior. The manual mechanism 4 and the electric mechanism body 3 are respectively set on the inner sides of the left and right ends of the mechanism box 1. This makes the mechanism structure compact, saving installation space and making it convenient for users to install. The manual operation disc 5 is connected to the mechanism box 1 through the pin shaft 6. The manual operation disc 5 has an arc-shaped notch 501. The outer end of the manual operation disc 5 has a circumferential surface 502 with two limiting grooves 503. The lower part of the manual operation disc 5 is provided with a locking pin 7 that engages with the mechanism box 1. The locking pin 7 is telescopically connected to the mechanism box 1 via a return spring 8. The outer shape of the upper end of the locking pin 7 is the same as the inner shape of the limiting groove 503. Therefore, when the mechanism is in the open or closed position, the locking pin 7 is pushed into the limiting groove 503 under the action of the return spring 8. When the mechanism is in the open or closed position, the manual operation disc 5 is locked, thus ensuring that the open or closed position is correct.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 A semi-circular block 9 is fitted to the front side of the locking pin 7 and located on the lower front end of the manual operation disc 5. The electric mechanism spindle 10 is mounted on the inner side of the semi-circular block 9. The two ends of the semi-circular block 9 are a straight edge 901 and an arc contour 902, respectively. The outer arc of the arc contour 902 is the same as the inner arc of the arc-shaped notch 501. Therefore, when the disconnecting switch is in the closed position and the grounding switch is in the open position, the arc contour 902 of the semi-circular block 9 on the electric mechanism spindle 10 engages with the arc-shaped notch 501 on the manual operation disc 5. This is to prevent the manual operation disc 5 from being locked and thus inoperable. When the switch is open, the straight edge 901 of the semi-circular block 9 faces the manual operation disc 5, making it impossible to lock the manual operation disc 5. The manual operation disc 5 can then operate the grounding switch to close. When the grounding switch is closed, the circumferential surface 502 of the manual operation disc 5 faces the straight edge 901 of the semi-circular block 9, so that the semi-circular block 9 is locked during motor operation, preventing motor operation. This facilitates the interlocking of grounding and isolation operations. All the electrical components mentioned above are existing technologies and will not be described in detail here.
